WINDIVIILL-REGULATING PUMP.

SPECIFICATION forming part of Letters Patent No. 621,789, dated March28, 1899.

Application filed September 20, 1898. Serial No. 691,453. (No modell) Toau whom it may concern:

`Be it known that I, GEORGE P. BUMP, a citizen of the United States,residing at South Superior,county of Douglas,and State of Wisconsin,have invented certain newand useful Improvements in VVindmill-RegulatingPumps, of which the following is a specification.

My invention relates to a regulating windmill-pump of that class inwhich the Windmill is thrown into and out of action by the variation ofpressure in the pipe system.

The object of this invention is to provide a regulating-pumpof which theparts are of cheap, simple, and durable construction and easilyassembled, to provide a regulatingpump in which the packing-glands willnot leak when heavy pressure comes on them and do not need to be kept sotight as to interfere with the plunger of the pump in which theregulating-cylinder is placed, so that sand or sediment cannot settle inthe bottom and clog it and stop its working 0r' break it, and in whichthepiston and working parts are placed centrally of the pump-stand, soas to avoid side strain on the pump.

The invention is illustrated in the accompanying drawings, in Which-Figure l is an elevation of the cylinder with parts broken away to showthe working parts. Fig.l 2 is an elevation showing the regulating deviceattached to an Ordinar three-way pump. v

In the drawings, Zlare the pump members, and A is theregulating-cylinder supported between them.

B is a piston and cylinder combined Working in the cylinder A, and O isa coupling attached to a connecting-link I,connecting with a lever H,which is attached to a wire J, which extends up to and controls themill.

K is a weight to pull mill in gear and hold it while water-pressure isoff.

L is the delivery-pipe extending to the ordinary tank, (not shown,) andF is the pumprod extending through the regulating cylinder and piston tothe pump-cylinder. (Not shown.) Y

D isan outlet-opening designed on the extreme rise of the piston underexcessive pressure to permit the escape of the water and preventbursting.

In the operation of the device when the water ceases to flow throughpipe L, with the mill still running, the water-pressure causes combinedpiston and cylinder B to rise,which being attached to lever H rocks thisand pulls down on J and throws the mill out of gear, and as soon as theWater-pressure is released Weight K forces the water out of the cylinderA and slacks the wire J and lets the mill go back in gear.

By this arrangement it will be observed that the regulating-cylinderlisarranged centrally of the pump and is effectively braced by the sidemembers thereof, dispensing with any additional outside castings as areordinarily used, the strain on the pump -is lessened, and a guide isprovided for the pump-rod.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent of the United States, is-' l. Inawindmill-regulator, the combination with the pump, of aregulating-cylinder connected therewith in line with the pumppiston-rod, and a piston working in said cylinder with connections tothe windmill, the said pump piston-rod passing through said regulatingpiston and cylinder, substantially as described.

2. In a windmill-regulator, the combination with the pump, of aregulating-cylinder connected therewith in line with the pumppiston-rod, and a hollow piston working in said l cylinder withconnections to the windmill, the

said pump piston-rod passing through said regulating piston andcylinder, substantially as described.

3. In a windmill-regulator, the combination with the pump having theside members of the regulating-piston arranged Abetween the same, thehollow piston working in said cylinder, the weighted rocking leverpivoted to one of the pump members, a connection between said lever andthe windmill, and a connection between the lever and the' hollow piston,substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

.GEORGE P. BUMP.'
